Zhafir ZE 1900 III / 640h Electric Injection Moulding Machine – Technical Evaluation (Year 2020)
1. Technical Evaluation Overview
The Zhafir ZE 1900 III / 640h is described as a fully electric injection moulding machine manufactured in 2020, with 6,000 hours under power and a stated condition of “like new.” Based strictly on the provided information, the machine is presented with a clamping force stated as 1900 (reported inconsistently as 1900 T and 1900 kN), a mold opening stroke of 470 mm, and platen dimensions of 940 × 940 mm.
Injection unit data lists a shot volume of 412 cm³ and shot weight of 375 g, with pressure on material reported as 17 MPa. The machine envelope is 6,300 × 1,600 × 2,300 mm, with a machine weight of 9,300 kg. Ejection capability is specified with an ejector stroke of 150 mm and ejector force of 55 kN.
Important note on data consistency:
Several critical specifications are internally inconsistent and require verification before any technical conclusion:
Clamping force is alternately stated as 1900 T and 1900 kN (these are not equivalent).
Distance between tie bars is reported as 370 × 370 mm in one section and 570 × 570 mm in another.
Screw diameter is stated as 500 mm, which is not technically consistent with the given shot volume of 412 cm³ and must be confirmed.
Due to these discrepancies, the exact capacity class and injection unit configuration cannot be conclusively defined from the provided data alone.
2. What to Check Before Buying
Given the inconsistencies and the importance of precise specifications in injection moulding, the following checks are essential:
Clamping unit:
Verification of the actual clamping force (kN vs tonnage) via machine nameplate and control data.
Measurement and confirmation of tie bar spacing, minimum/maximum mold height (200–550 mm), and maximum daylight (1020 mm).
Inspection of platen flatness and alignment, considering the stated 940 × 940 mm platen size.
Injection unit:
Confirmation of the actual screw diameter and injection unit size, ensuring consistency with the stated shot volume (412 cm³) and shot weight (375 g).
Verification of injection pressure capability and material pressure data (17 MPa stated).
Functional testing of plasticizing, injection repeatability, and recovery behavior.
Ejection and mold handling:
Performance of the ejector system across the full 150 mm stroke and 55 kN force.
Compatibility of the machine with molds at the stated minimum mold size of 370 × 370 mm.
Electrical and control system:
Review of operating hours (6,000 hours under power) via the control system.
Functional testing of all-electric drives, axis synchronization, and alarm history.
Availability of parameter backups and machine documentation.
3. Typical Industrial Applications
Based strictly on the stated shot volume and electric configuration, the machine is technically aligned with:
Precision injection moulding of medium-sized plastic parts where repeatability and energy efficiency are required.
Applications benefiting from all-electric drive characteristics such as consistent cycle behavior and controlled motion profiles.
Specific material suitability, cavity counts, and production rates cannot be determined from the provided information and must be validated after resolving the specification conflicts.
4. Common Risks in Used Machines
For used electric injection moulding machines of this class, typical risks include:
Specification mismatches between documentation and actual machine configuration, as indicated by the conflicting data provided.
Wear in electric servo drives affecting repeatability if maintenance history is incomplete.
Injection unit misidentification, which can lead to incorrect mold or material matching.
Incomplete documentation, especially regarding injection unit size, clamping force rating, and control parameters.
5. Maintenance and Service Considerations
With no detailed service records provided, only general technical considerations can be stated:
Electric drive systems require verification of servo condition, cooling efficiency, and axis calibration.
Regular inspection of tie bars, platens, and ejection mechanisms is essential for maintaining mold alignment.
Machine parameters and production data should be backed up prior to operation.
Any maintenance or production planning should be based on a full on-site inspection and confirmation of the correct technical specifications, not assumptions derived from conflicting datasheets.
Final Note:
While the Zhafir ZE 1900 III / 640h is presented as a modern, low-hour electric injection moulding machine, the provided specifications contain significant inconsistencies. A reliable technical evaluation requires verification of clamping force units, tie bar spacing, and injection unit configuration through direct inspection, nameplate confirmation, and control system review.
